What is the maximum allowable temperature for fuel?

The maximum allowable temperature for fuel in the King Air 350 is set at 50°C. This limit is crucial for maintaining the integrity and performance of the fuel system. Fuel overheating can lead to a variety of issues, including reduced fuel efficiency, increased risk of vapor lock, and potential engine malfunctions due to improper fuel characteristics at elevated temperatures.

Keeping the fuel temperature within the specified limit ensures optimal performance, reliability, and safety of the aircraft. Therefore, adherence to this limitation is critical for flight operation in various temperature conditions, contributing to the overall operational efficiency of the King Air 350.
